Methods, systems, and articles of manufacture to enhance automation of conversion and/or persistent storage of color management information embedded within an associated, received data object. Features and aspects hereof provide that color management information embedded within an identified data object (e.g., an image data object) is converted to an appropriate form useful within the printing environment and persistently stored for re-use in conjunction with presentation of received data objects in a print job. For example, an icc profile embedded within a received image data object may be converted to an afp color management resource (a color conversion cmr and/or zero or more link CMRs) and persistently stored in an object library for re-use in presentation of print jobs. The conversion and persistent storage of such color management information may be substantially automated as a step in the installation of the underlying data object.

1. Field of the Invention
The present invention relates color management information in a printing application environment and more specifically relates to improved generation and utilization of color management resources from color management information embedded within presentation objects in a printing application environment.
2. Discussion of Related Art
In a printing environment a printing system coupled to one or more attached host systems and/or associated servers may imprint information on a printable medium such as paper. The information to be imprinted may include textual information as well as graphical or image information. Collectively or individually, all such information may be referred to herein as “presentation objects” or as “data objects”. Additional received information specifically relating to color printing may be received. Meta-data objects may be associated with presentation objects to be printed such that the meta-data helps, for example, to standardize the desired color output. In one common approach, an International Color Consortium (ICC) profile may be supplied by the application that generates the print source data (the “presentation data”). In general the ICC profile defines standardized color parameters associated with the particular data to be presented and associated with the particular application or device that generated the initial presentation data. For example, digital cameras and scanning devices may digitize an image into any of several well-known encoding formats and may also generate a corresponding ICC profile representing the color parameters of the camera or scanning device. Using the ICC profile of the generating device or application, the printing system may then computationally map the parameters of the generating device into corresponding parameters for the printing device intended to present the corresponding textual or graphic information with the desired colors faithfully reproduced.
In many printing application environments, standard portions of information to be imprinted may be setup as an initial task prior to printing a print job or even prior to generating the print job. For example, a collection of images such as digital photographs, scanned images, graphical art (such as corporate or product logos), etc. may be initially defined and setup as reusable objects defined in an object library. When these objects include color information (e.g., color attributes applied to textual or graphical objects), an ICC profile may be supplied to define color parameters to permit accurate reproduction of the color when the object is eventually applied to a printing device for imprinting on a medium. In general, when a printing system uses an ICC profile regarding the color characteristics of a generating device or application, the printing system performs substantial computation to translate, transform, or convert the supplied color parameters into associated color parameters for the printing device. The computation and transformation associated with such color parameter information helps assure that the printing system produces the desired colors as accurately as possible in accordance with the standardized defined reference values.
In view of the substantial computations involved with transforming or converting such color parameter information (e.g., the ICC profile of the generating device for application), it is desirable and common to reduce or minimize duplicative computations for such transformations and conversions—especially if the same ICC profile is to be used in conjunction with multiple data objects. For example, the printing system may convert or transform the associated color parameters of the ICC profile into an appropriate format for later use by the printing system. More specifically, for example, when an Advanced Function Presentation (AFP) environment is provided with an ICC profile, the color parameter information of the ICC profile is converted into a corresponding AFP color conversion color management resource (a CMR or more specifically a “CC CMR”). In the AFP environment, a “link CMR” may also be pre-computed that incorporates color management information regarding the translation from an input device CMR (i.e., the device or application that generated a data object) into the color management information related to each specific printing device on which a print job may be presented. A link CMR is known in the AFP environment as an enhancement that pre-computes the conversion of color data from an identified input device into appropriate color information on a particular output device. Thus zero or more link CMRs may be precomputed for each identified input device to map the color information to one or more possible output devices (e.g., one or more identified printer systems or other presentation devices). Multiple data objects may reuse that same ICC profile and thus the same generated CMR structures may be reused to reduce computational loads when a print job is later processed using the stored data objects. Thus the ICC profile information is converted (translated or transformed) into a format that may be reused by an AFP printing device and that minimizes computational load on the printing device.
The pre-computed CMR objects (e.g., CC CMR and zero or more link CMRs) are also saved in the object library of an AFP environment for later reuse when printing a print job that references the converted ICC profile. In particular, for an AFP compliant printing system, data objects and ICC profile objects (as converted to CC and link CMRs) are stored in the object library of the AFP enterprise.
As presently practiced, the AFP resource installer (as well as similar object or resource installers or creators) processes data objects to be stored in the object library as a separate and distinct matter relative to the processing of an ICC profile. In other words, a user invokes the data object installer portion of the AFP resource installer (also referred to herein as a data object installer wizard) to install data objects. The user also separately invokes a CMR object installer portion of the AFP resource installer (also referred to herein as a CMR object installer wizard) to convert ICC profile objects into CMR objects and the install the CMR objects in the object library. The data object installer also interacts with the user to associate the installed CMR object with any related data objects in the object library. Typically, data objects and ICC profiles are received as separate objects provided by the user of the AFP resource installer modules. Thus, an ICC profile when separately received by an AFP printing system will be transformed into an appropriate CMR and stored for subsequent utilization. When presentation objects are provided by a user that reference an earlier provided ICC profile (now converted to a corresponding CMR object in the object library), the data object is processed by the data object installer in the object library.
In some situations, the ICC profile may be embedded within the data object to be presented. For example, in one common approach, a tagged image file format (TIFF) presentation object may be generated by a scanning device or digital camera (or any other suitable means or application program for generating a TIFF presentation object). The ICC profile for the device or application that generates the TIFF image may be embedded with the TIFF image data. Interactions with a user of the resource installer are less straightforward when a presentation object has embedded color parameter information (e.g., a TIFF presentation object with an embedded ICC profile). In present print setup applications such as the AFP resource installer, the user/operator is required to invoke a data object installer portion of the resource installer to install the TIFF image as a data object. The user must then manually extract or otherwise provide the ICC profile information to apply it as input to the manually invoked CMR installer portion of the resource installer. In other words, in current systems a first manual operation may be required of an operator to store a data object such as an image data object and a second manual operation is required of an operator to store color management information (e.g., the ICC profile as converted to the printing system's preferred format). The inconvenience and duplicative operations demanded of such a user may give rise to opportunities to introduce errors and/or may impose a further burden on a user/operator of the printing system
It is evident from the above discussion that improved methods and systems are required to reduce the burden on the operator/user of the print setup application and to thereby reduce the opportunity for human error in persistently storing a data object and associated color management information embedded in the data object.
The present invention solves the above and other problems, thereby advancing the state of the useful arts, by providing methods, systems, and associated articles of manufacture for substantially automating the process of generating and persistently storing (in an object library) color management information embedded within a received object. In one exemplary embodiment, color management information such as an ICC profile may be embedded within a graphical presentation object to be persistently stored in the object library. The user may invoke an object installer to install the image data object. Features and aspects hereof detect the presence of such embedded color management information and automatically direct the user to select appropriate options for automatically converting and/or saving the embedded color management information. The embedded color management information may then be removed from the data object in the object library to reduce the storage requirements and the associated data transfer time when transferring the stored object to a presentation device. Another exemplary embodiment specifically provides for enhancement of an AFP resource installer adapted to receive presentation objects having embedded ICC profile information (e.g., color management information). The AFP resource installer program product may be enhanced in accordance with features and aspects hereof to detect the presence of the embedded ICC profile and to automatically guide the user through installation (e.g., persistent storage) not only of the underlying presentation object but also through the steps to convert and persistently store an AFP color management resource (CMR) object derived from the color management information embedded within the received presentation object. The CMR object so generated and persistently stored may later be used by the printing environment when printing the data object in which the underlying color management information was embedded as well as other data objects that rely upon the same color management information.
In a first aspect hereof, a method is provided for installing objects in an object library of a printing environment. The method includes receiving from a user a data object having embedded color management information. The method then stores the data object in an object library of the printing environment. The method also detects the presence of the embedded color management information in the received object. The method also generates a color management resource (CMR) wherein information in the CMR is derived from the embedded color management information. The method also stores the CMR in the object library for re-use within the printing environment in conjunction with presenting objects of a print job. The method steps of detecting, generating, and storing the CMR are performed automatically in conjunction with the step of storing the data object.
Another aspect hereof provides a method for storing objects in an object library of an Advanced Function Presentation (AFP) printing environment. The method includes receiving from a user a presentation object having an embedded International Color Consortium (ICC) profile embedded within the presentation object. The method then determines whether the ICC profile corresponds to a stored AFP color management resource (CMR). The method then associates the corresponding stored AFP CMR with the presentation object in response to a determination that the ICC profile corresponds to a stored AFP CMR. Responsive to a determination that the ICC profile does not correspond to any stored AFP CMR, the method then continues by automatically generating an AFP CMR wherein information in the AFP CMR is derived from the ICC profile and associating the generated AFP CMR with the presentation object. The method then stores the presentation object and the AFP CMR in an object library of the AFP printing environment for re-use in conjunction with presenting objects of a print job.
Print object setup application 102 may physically reside within any of several processing elements of a printing environment including any of various user application computing nodes, compute server nodes, print server related nodes, etc. Further, any number of such computing nodes or devices may be distributed in an enterprise for processing of print jobs. Numerous such printing environments are well known to those of ordinary skill in the art including, for example, an InfoPrint printing environment, and AFP environment. Such distributed network processing and program paradigms are well known to those of ordinary skill in the art. In particular, the resource installer 106 and the object library storage 114 may both physically reside within the same computing node or may be distributed over any number of computing nodes and servers.
User 150 interacts with resource installer 106 utilizing the data object installer 112 portion of the resource installer 106 to persistently store a data object for subsequent use in presentation of objects of a received document. In addition, user 150 may interact with ICC profile installer 108 to generate and install a color management resource (CMR) for persistent storage and subsequent use in presentation of the associated document. A CMR generator 110 may be associated with the ICC profile installer 108 to generate an appropriate CMR object at the direction of user 150.
After setting up data and/or CMR objects in the object library 114, a print data source 104 (i.e., a print job) may be generated by an application (not shown) that utilizes the objects in the object library 114. A job processor (rasterizer, spooling and print control element 116) may process the print data source 104 and access the objects in object library 114 to process the print job for application to a marking engine 118 (or other presentation device).
As noted above, as presently practiced in the art and as depicted in
Elements 210 through 214 represent a separate and distinct process invoked by a user and interactive with the user to install in the object library color resource management objects extracted or otherwise derived from color management information associated embedded within the installed data object. Element 210 represents processing by a user to extract the color management information embedded within the data object just installed by the user. The embedded color management information may be, for example, an ICC profile for the device or application that generated an image represented by the data object just installed. Element 212 then generates a CMR object derived from the color management information. The CMRs are generated by copying and appropriately translating the ICC profile information embedded in the data object. Element 212 also represents processing by the user, again invoking the resource installer, to interact with a CMR installer portion thereof to install the CMR in the object library. Element 214 then represents processing by the user, interacting with the data object installer, to associate the newly installed CMR object with the previously installed data object in the object library. Those of ordinary skill in the art will recognize that the generated CMR objects and the data objects may be stored in a single, common object library or may be installed in separate, corresponding object libraries (e.g., a data object library and a separate CMR object library). Such design choices will be readily apparent to those of ordinary skill in the art.
As noted above the two separate and distinct processes each require substantial manual intervention to identify data objects, to identify associated color management information, to persistently store the identified objects and color management information, and to associate the identified objects and information as required for processing. Such manual processing burdens a user and creates numerous opportunities for human error.
By contrast,
The CMR object generated by processing of element 310 may then be persistently stored in the object library by operation of element 312. The stored CMR object may then be referenced by data objects in subsequent processing of a print job in association with rendering of the received data objects. Lastly, element 314 is operable to associate the data object that included the embedded color management information with the newly generated, persistently stored, CMR.
